CRUSHER.

Specification of Letters Patent.

Application filed October 10, 1912.

Patented Feb. 24, 1914. Serial No. 725,018.

To all whom it may concern Be it known that I, OLIVER J. MoUssET'rE,

I a citizen of the United States, residing at Brooklyn, in the county ofKings and State of New York, have invented certain new and usefulImprovements in Crushers, of which the following is a specification.

This invention relates to crushers or pulverizers, and has for itsobject the provision of a comparatively simple and thoroughly eflicientmachine which may be used for grinding ores or similar material and willbe especially adapted for reclaiming brass or other metal from therefuse of refineries, foundries, smelters, and the like.

- The invention has for one object the provision of a crusher soconstructed that the finely ground material may be fed from between thecrushing members as it is pulverized and deposited in a suitablereceptacle.

The invention also seeks to provide a crusher so constructed that thematerial being treated will be continuously acted upon by the crushingmembers and the collection of the unground material between the activecrushing members in such quantity as to arrest the action of the machinewill be prevented.

The invention also seeks to provide a crusher of the rotary drum typewhich may be easily operated, and also seeks to improve, generally, theconstruction and operation of crushing machines to the end that theefliciency and durability of the same may be increased.

The several stated objects of my invention, and other incidental objectswhich will ap pear as the description of the invention proneeds, areattained in an apparatus of the type illustrated in the accompanyingdrawings, and the 'lIlVGIltlOll res1des 1n certam novel features whichwill be hereinafter full disclosed. and particularly pointed out in theclaims following the detailed description.

In the'drawings: Figure 1 is an elevation of a crusher embodying mypresent improvements; Figs. 21s a /plan view of the same; Fig.- 3 is avertical longitudinalsection; Fig.

4 is a transverse vertical section; Fig. 5 is an enlarged sectional viewthrough the outlet controlling rings and the screen showing the partsseparated and in their proper relative positions; Fig. 6 is a detailperspective view of a portion of one of the outlet controlling rmgs.

In carrying out my invention, I employ a supporting frame or base 1which is pref erablyconstructed of. a single integral casting)comprising corner posts, a transverse we 2 connecting the posts at the.ends of the frame, and a longitudinal brace or connectlng bar or Web 3extending between the said webs. Upon the upper ends of the posts areprovided journal boxes 4 whiohreceive. and support the parallel shafts 5extending longitudinallyof the frame at the opposite sides thereof. Uponthese shafts, adjacent the ends of the frame, are flanged rollers orwheels 6 through which motion is imparted to the drum. Between therollers or wheels 6, at one end of the supporting frame and the adjacentside of the housing 7, sprocket wheels 8 'are fittedrigidly upon thesaid tion, and, as there are no unnecessary parts;

the cost of installation and maintenance is minimized. It will also benoted that the described arrangement brings the sprocket chain and thewheels upon which it is trained below the drum so that the employment ofa casing or housing for the driving gearin is rendered unnecessary.

The ousing 7 fits around the central longitudinal brace 3 of thesupporting frame and projects upwardly therefrom to extend around thedrum 13. Rings 14 of leather or heavy cloth are secured to the sides of,the housing and fit closel to the drum to prevent escape of dust. heserings may be secured in any desired manner, preferably by clamping ringsand bolts, as shown in Fig. 3.

fixed head or closure 19, as shown. The terpast the same when-t e drumis in use Wlll receptacle A receptacle is placed below the brace 3 andis fitted closely to the lower end of the housing so that the leakage ofthe finely ground'matter between the housing and the cannot joccur. Thedrum issupported upon and driven by the rollers 6 and consists of theinner tapered or substantially conical sections 16 having the drivingrings 17 formed at their outer smaller ends to bear directly upon therollers 6 so that, when the said rollers rotate, the rotary motion willbe imparted directl to the driving rings and the drum there y rotatedabout its own axis. As the shafts are connected by the s rocket chainand wheels above described,

both shafts will be positively rotated and, consequently, the rollers onboth shafts will .beactuated and slipping of the drum upon some of therollers, with the consequent frictional wearin away of the contactingsurfaces, isavoi ed.

Secured rigidlyto the outer ends of the drum sections. 16 are terminalmembers 18 .whicha're of similar tapered or conical formation and one ofwhich is provided with a minal member 18 at the opposite end of the drumhas-rigidly secured thereto atubular tenal ma member 20 which ispreferably in the form of a spout, as shown in Fig.3, so that mabereadily fed into the drum through t e said spout or feed "member, as

will -be readily understood. This feed or inlet member or spout isclosed by a cover or lid 21 which is pivoted to the upper end i of asupporting armor standard 22 rising said log or cam and, consequentlyfromthe base the said lidor cover is formed a ra 'al proj'ection or cam23 whieh abears against a spring presser plate secured upon the arm 22.The projection or cam 23 is so i sposed that when the cover 21 is swungnpwardl against the end of the inlet member-120 the orce of the springplate 24 will be directed downwardly agains't the the cover will beheldfirmly against the mlet of the drum so as to close the same and preventthe escape of material therethrou h. If the lid or cover be swund'ownwar y against .the pressure of the said plate 24, the plate willyield to the upward outward movement of the'lu and will thenbear upontheunderside 0 the said lug or cam so that the premature closing'of thelid-or cover will be prevented. .It will thus be seenthat I haveprovided an exceedingly. simple device by which the lid or cover may beheld in either o'fits; positions s0:that premature closing bf the samewill be rev'ented and leakage also be prevented andthe use of packin andexpensive locking devices is rendere ame 1. .'Upon the ivot of thereason that, while the spring presser plate will hold the lid or coverin the position in which it may be set, the plate will yield readily tomanual force exerted upon the lid to shift the same.

The inner ends of the main section 16 of the drum do not abut, but arespaced from each other to accommodate a pair of rings or disks 2;) whichaid in the crushing of the material and also control the discharge ofthe crushed material. These rings or disks are provided on their opposedinner faces with spacing lugs 26 which, by being placed in contact,holdthe disks or lugs slightly separated and thereby provide anintermediate passage 27 through which the ground material may escape.The lugs, furthermore, constitute additional breaking members which willbe brought against the particles passing into the space between thedisks by'the rotation ofthe drum with such force as to furtherdisintegrate the same. The inner faces of the disks are inclined orbeveled so that the space 27 flares toward the outer edges of the disksand, consequently, the particles passing beyond the lugs 26 at the inneredges of the disks'may readily pass from between the same. At the outeredges of the disks are provided additional spacing lugs 27 and theselugs 27 not only aid in holding the disks. in their spaced relation,but,also reinforce the disks by providing enlargements through which thesecuring bolts 28 may be passed to secure the disks in position. In theouter faces of the disks or rings are formed a plurality of radialgrooves 29, the outer ends of which are flared, as indicated at 30, andthese grooves constitute outlets for the material, as" will be readilyunderstood. A screen 31 is arranged concentrically around the drum, andthis screen is preferably constructed of a sheet metal plate havingsmall perforations or openings 32 terial. The screen is held in spacedrelation to the drum and the outer peripheries of the disks or rings 25by a series of brackets 33 having their inner ends fitted upon the bolts28 and secured by the said bolts against the annular radial flanges 34formed on the main sections of the drum, the outer ends of the saidbrackets 33 being extended axially with respect to the drum and fittedin the grooved collars 35 which also fit over the edges of the screen.Set-screws 36 are mounted in the outer sides of these/collars and engagethe screen so as to pass through the edges of 'the same and bear uponthe ends of the brackets whereby the screen and the brackets will besecurely clamped within the collars and the screen thereby supportedupon the drum. It will also be noted that the bolts 28 secure thebrackets to the drum and the innermost sections of the drum, as well asthe rings interposed between. the said sections, together. a

' The screen extends close to the upper por tion of the housing 7 whichis imperforate and is preferably cylindrical in form, while the lowerportion of the housing is shaped to provide converging walls serving asguards to deflect the material escaping through the screen into thereceptacle 15 placed below. the housing. The housing is provided with aman-hole 37, and a portion of the screen, indicated at 38, is made toserve as a door by being cut out of the main portion of the cylindricalbody of the screen and hinged thereto so that if it be necessary toclean 'or repair the' itcreen or the drum,

the drum and screen may be rotated so that the door 38 will be made toregister with the man-hole 37 and, access then may be had to theinterior of the drum, as will be readily understood.

Crushing rollers 39 are mounted loosely within the drum and thesecrushing rollers may be of the usual conical form. The rollers. restloosely within the drum upon the bottom portion thereof and have asomewhat greater taper than the main sections of the drum so that theinner opposed ends of the rollers will flare upwardly with respect toeach other. These larger ends of the rollers are preferably corrugatedor otherwise roughened,as indicated at 40, so that'as the rollers rotatethe material cau ht between the same will be thoroughly bro on up andreduced. The said inner ends of the rollers are constructed with centralconcave recesses 41 which receive the eyes 42 on the inner ends ofeye-bolts 43 passing through the central bores of the rollers and of adiameter to substantially fill the said bore, but, at the same time,permit free rotation of the rollers. Nuts 44 mounted on the outer endsof the bolts serve to retain the bolts in position within the rollers,and a link- 45 is fitted through the eyes 42 of the bolts andextendsbetween the same so that the rollers will be effectually coupledand held in their proper relative positions with ofthe said spout so asto close the same, as previously stated. The power of the prime motoristhen transmitted to theshafts 5 by shiftir the driving belt onto thefast pulley, an' thesaid shafts-will then conse- -be rotated. Therotation of th? saidis afts being imparted directly to the Yesrollersfor supporting wheels 6, the drum will immediately be set inmotion through the frictional engagement between the said rollers andthe driving rings 17 on the drum. The material fed into the drum willtend to accumulate in the lowest point of the same and will,consequently, be caught between the two crushing rollers, between therollers and the sides of the breaker rings or disks, and also betweenthe bottom of the drum and the rollers so that the weight of the rollerswill be exerted to.

will carry the same around so that they will be again deposited upon thebody of ma terial in the drum, the result being that only smallparticles will be permitted to escape to the screen and any particleswhich are too large to pass through the screen will be subjected to arolling disintegrating action through the rotation of the lugs 27 at theouter ed es of the disks and will also return to t e interior of thedrum to he again treated. The finely ground material escaping betweenthe rollers and the bottom of the drum will enter the radial grooves onthe outer faces of the disks and will escape through the same readilyand rapidly to the screen. It will also be noted that the screen isrigidly connected with the drum and consequently rotates with it so thatthe particles of matter too large to pass through the screen will becarried around and dumped upon the upper portions of the rings or disks25 where they will enter the space between the disks and settle upon thelugs 26. tending to pass between the said lugs and consequently beinbrought into position to be broken up by the lugs and the rollers.

My improved crushing machine is composed of very few parts and will befound highly eflicient in use and its many advantages are believed to beevident from the foregoing description without further detail mention ofthe same.
